Does the water touch plastic in any part of the machine?
There is no plastic in the fluid/material path of either machine - it's virtually all stainless steel and silicone. Basically the only plastic on them is in the switches/electrical parts where is is almost impossible to avoid.
I think the plastics we have noticed to be harmful are only the ones that are the most obviously biologically disruptive or carcinogenic. Not sure anyone building anything now can confidently say that the plastic they're using won't be a problem later on.
I'm also slightly skeptical of aluminum when in contact with acidic fluids but that's a whole different thing.
Wow, thank you for building this, with stainless steel you have addressed the last concern I had for the grinder (well, the price is a bit steep for me too, but I can understand it).
Btw, is it Turbina or Oculo? Chart and shop say Oculo, bit it's Turbina elsewhere.
Thank you for noticing this, Oculo was a working name when the hopper looked more like an eye but now it doesn't! Clearly I've left some random references to the old name around. Could you point me to where in the shop it says Oculo?
In the chart where you compare the "total burr area", and then... Hmm, I could swear that the shop said that it is coming in march 2025, and used the name Oculo there? Sorry, can't find it anymore.
You're right when you factor in the power brick, but the wiring is actually silicone jacketed which is much nicer in any case! The main plastics are in the switches inside the machine. Would be fun someday to roll custom ceramic parts for those but for now, keeping scope creep to a minimum!
